edit: needed put data type json? new json too...

try code :

javascript :

function getpath() { if (!window.location.origin) {     window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port : ''); } var domainpath = window.location.origin + "/"; if (domainpath.indexof("localhost") == -1) {     return domainpath; } else {     return domainpath; } } 

ajax:

you path in getpath() method.

var path = getpath(); $.ajax({                 type:'post',                 contecttype: "application/json; charset=utf-8",                 datatype: "json",                 url: path +"room.aspx?board='" + roomcode + "'",                 data: "{'roomcode':'" + roomcode + "','uname':'" + username + "','msg':'" + <%=message.clientid %> + "'}",             })
